Markdown syntax highlighting for ordered and unordered lists only handles 2 spaces and 2 levels

[mdpenguin]

Issue

• Bullet or numbers only get highlighted on columns 1 and 3.
• Anything from column 9 on-wards gets highlighted like code.
• It doesn't seem to matter whether spaces are set to 2 or 4 or any other number.
